It is cooled to room temperature;Described first refrigerating work procedure: use water-cooled, air-cooled cooling with aerosol to combine, first use water-cooled with 7-9 DEG C/s's
Steel plate water-cooled to 950-970 DEG C, is then used the cooldown rate of air-cooled 5-7 DEG C/s that slab is cooled to 720-780 by cooldown rate
DEG C, then use aerosol to cool down the cooldown rate with 1-3 DEG C/s by steel plate water-cooled to 600-620 DEG C;Described second refrigerating work procedure:
Use compressed air or vaporific quenching liquid, with the cooldown rate of 12-15 DEG C/s, steel plate is cooled to room temperature.
6. bulb flat processing tool as claimed in claim 5, it is characterised in that: described upper gusset and lower web plate surface scribble anti-
Corrosion composite coating;
The mass percent component of described corrosion-resistant composite coating is: 4-isocyanatomethyl: 11~13%, amino first
